IMPROVEMENT lN CARBURETING ATTACHMENTS FOR GAS-BURNERS.

Specification forming part of Letters Patent No. 203,456, dated March21, 1878.

To all whom it may concern:

Be it known that I, CHARLES HOFF, of Oincinnati, Hamilton county, Ohio,have invented a new and useful Improvement in Carbureting Attachmentsfor GasBurners, of which the following is a specification:

This is a device for charging ordinary illuminating-gas with the vaporof gasoline, by

causing a very small stream of the gas to pass through wicks or spongesaturated with gasoline.

The accompanying drawing represents a section of a carburetor embodyingmy improvements.

A is a suitably-formed vessel for holding gasoline, and is securelyattached to a cut-01f cock, B, on the end of the service-pipe G. Fromthe lower end of the vessel A any suitable gas-fixture, D, may besuspended. Opening into said fixture, and projecting up into the vesselA, is a hollow stem or tube, E, having perforations at, e to admit thegas. This tube supports a vaporizer, consisting of an annular cup-shapedvessel, F, (which contains shavings, sponge, wool, or any similar porousmaterial, G,) and of several wicks, H, attached by rivet h to theelevated center of the cup,

' and projecting over the edge of the cup down into the liquid in thevessel A.

The gasoline is introduced into the vessel A through the stopperedopening I, which is placed low enough to prevent the liquid from flowingthrough apertures 0 into the pipe E.

The amount of gas entering the carbureter is regulated by the cock B,which also serves to temporarily out off the gas while the ves sel isbeing filled.

In the use of this attachment the greater May 7, 1878 application filedpart of the illumination is due to the gasoline, the office of the gasbeing chiefly, by its flow in contact with the saturated capillaries, todetach and carry forward the gasoline vapor. 7

By this arrangement of wicks and sponges a large amount of surface isexposed to the gas, which consequently becomes heavily im pregnated withthe vapor of gasoline, which forms a better, and at the same timecheaper, flame than the gas alone would do.

Whenever the vessel A becomes depleted of gasoline, it can bereplenished at short notice by first closing the cock B, so as to stopfor the moment the flow of gas, and then opening the stoppert' andpouring in a new charge of gasoline.

I prefer, in addition to the wicks, to fill the lower chamber to levelof charging-hole with fragments of wood charcoal about the size of anavy bean.

I claim as new and of my invention- In combination with a carburetingattachment for gas-burners, the pendentgasolineholder A, communicatingby stop-cock B with service-pipe G, the inclosed hollow stem of tube Ecommunicating below with burnerarms D and above with said holder, andsurmounted by the annular vaporizing-trough F, for the reception ofsponge G and wicks H, or other suitable capillary devices.

In testimony of which invention I hereunto set my hand.

CHARLES HOFF.
